Research has shown that noise exposure among firefighters results in greater risk of hearing loss than that expected from aging alone. As such, occupational health experts have recommended the wide implementation of hearing conservation programs for firefighters, including the use of HPDs and engineering controls to reduce noise exposures [16–19, 21–23]. Current advanced technology for firefighters includes two-way communication systems or vehicle intercom systems. These systems are designed to facilitate clear speech and to simultaneously attenuate siren and vehicle engine noise, providing for hearing protection and clear communication both en route to and at the scene of a fire. However, despite NFPA recommendations, use of these HPDs is not required for every American firefighting service and focus group discussions with firefighters have suggested that they are not used consistently. Furthermore, firefighters consider that exposure to noise is a routine and acceptable part of their job and NIHL is unavoidable
